Sponsor's own description

The goal of this observational study is to assess clinical factors associated with the occurrence of impaired hypoglycemia awareness in adult patients with type 1 diabetes The main questions it aims to answer are: 1. Determination of the prevalence of impaired hypoglycemia awareness (IAH) in adult patients with type 1 diabetes in the Polish population. 2. Assessment of the clinical usefulness of commonly used standardized scales for the assessment of IAH. 3. Determination of the clinical factors associated with the occurrence of impaired hypoglycemia awareness in adult patients with type 1 diabetes. 4. Determination of the relationship between the occurrence of IAH and the diagnosis of cardiac autonomic neuropathy. 5. Determination of the relationship between impaired hypoglycemia awareness in adult patients with type 1 diabetes and the occurrence of cognitive impairment. Participants will: * fill the standard questionnaires regarding hypoglycemia awareness: Gold, Clarck, HypoA-Q. * have late complications of diabetes checked * have procedure of cardiac autonomic neuropathy assessment * have standard laboratory evaluation during hospitalization
